Heights, Ohio Application December 13, 1934, Serial No. 757,321 1 Claim.(01. 131-12) My invention relates,

and the like, such means stems, cigarette holder stems, cigar in itsbroadest aspect to for the bite end of pipes being adaptable to pipeholder stems and the like for the purpose of protecting the tongue andthe mucous membrane lining of the oral cavity of a smoker prevent thesmoke from out direct from In the smoking of a pipe from irritation, andto eri'ng into the mouth the pipe stem or holder. 1

and the like, it is a well known fact that all pipe stems and the likeat the bite end have a tendencyjo wear down the teeth of a smoker,

has no teeth, then th of the smoker.

Therefore the object of and further, bite end irritates the gums if thesmoker this invention is to provide a means whereby the smoke streamfrom a tobacco in a pipe bowl, orfrom a cigar or cigarete is hafiied ordiverted irom'a horizontal plane into a vertical plane,

plished by means of V smoke regulator.

It is also an object smoking? more pleasant by be diverted from oneplane verting thereof causing such diverting being a'ccomn expansionchamber in the of the invention to make causing the smoke to to another,such diit to eliminate some of the nicotine contained therein.

It is also a means on, in, or

an object of the invention to provide with a pipe stem smoke regulatorwhich will cause the smoke to cool before entering the smokers It isalso an object an attachment for the the like on the outside of themouth.

invention to provide bite end of a pipe stem and thereof which will savethe wear on the incisal or occlusal edges or surfaces of the teeth usedin holding a pipe or the like in the mouth.

1 upward into the egress and 'an efficient and compact is to permitmoist air from the oral cavity or mouth or a smoker to enter into theexpansion chamber, such tending to prevent a further rise of thepressure in the chamber, while at the same time serving as a regulatorso that the mixture of 5 smoke and moist air are simultaneously movedthence into the mouth.

It is also an object of the invention to provide smoke regulator for thebite end of a pipe stem and the like having an interlockingmeans thereinso as to enable it to be easily mounted on or in the pipe stemandinterlocked therewith, such mounting beingsimple in construction,easily manufactured-and easily re-v stem and integral therewith, andwhen thus zo made, then to insert or mount a covering means on theoutside of the pipe stem for the purpose of protecting the teeth of a.smokerfrom wear.

It is to'be observed therefore in the present type of smoke regulatorsfor use on pipe stems like, that their purpose is merely for sanitarypurposes as well as to save the teeth, so that other than the resultsoutlined the devices are generally considered unsatisfactory-from thestandpoint of a smokers comfort. ,Therefore to overcomesuch defects, thetype of smoke regulator used and which is the subject of this inventionis constructed of rubber, or rubber compound, or elastic plasticcompositions. It has considerable elasticity, and as well as being madeof the above compounds, it may also be made of any other suitablecompound or com- It is also an objector the invention to provide apounds means, which when placed 0 end of 'a pipe stem and the n, in, orwith the bite like will increase the length oi the smoke travel from thepipe bowl or the like to the mouth It is also an object of the a meanswhich may be attached or in a pipe stem and the like and of the smoker.

invention to provide a pipe stem and the the purpose of which In theinvent'on I find that elastic rubber is advantageous since it may beeasily molded into the 4 desiredshape and because of the conveniencewith which it may be applied and maintained in its desired position. Itismade to it on the outside with strict conformity to the shape of thepipe stem and/or the like, and may be mounted detachably thereon, or itmay be mounted in the end of the pipe stem, or it may be made integralwith the pipe stem. A conventional shape as applied to a standard pipestem ure 1, and from whichit will be observed that it comprisestop,side,bottom and an end wall which fits closely to the generalcontour of the stem end.-

It must fit snugly upon or in the bite end of a pipe stem so as toexclude air and moisture from 55 and the 25 illustrated in Figenteringin between the regulator and the pipe stem.

It may be of integral or composite structure, and 1 may likewise besuitably colored.

Other objects will present themselves, from a perusal oi thisspecification and claim, to those skilled in the art.

In the accompanying drawing, an illustrative example is shown of aconstruction of a pipe stem smoke regulator which will produce thedesired objects outlined above, and which when placed on the outside orinside of the stem will at the same time through its lnterlocklng'meansinterlock itself securely in place on or in the bite end of the stem.

In the device illustrated in the drawing, the pipe is divided into abowl portion 2 and a stem portion 3. Positioned at the bite end of thestem portion on the outside thereof is a bead or flange 5. Throughoutthe stem portion is a passage or bore 6 which communicates with the bowlof the pipe as shown. The pipe may be of integral or compositestructure. Positioned on or in the end portion of the stem portion andintegral or otherwise with, is a smoke regulator means 1. It will beobserved that the shape of the regulator is such as to encompass thestem snugly when used on the outside, and to fit snugly therein whenpositioned on the inside. On the regulator may be formed a bead means 8,the purpose of which is tostrengthen the regulator at that point. Theregulator has an internal recess 9 which cooperates with and snugly fitsand interlocks with the beadi on the pipe stem. Provided in theregulator is a mixing or air chamber l from which is an egress oraperture H, and a frusto conical or other suitably shaped ingress l2;The open end I! of the regulator is restricted in such a manner as toform an air tight and moisture tight joint between the pipe stem and theregulator. The frusto conical or other suitably shaped ingress l2 in theregulator is an air inlet and is positioned below the egress II.

When aregulator 20 is used to fit into the end of a pipe stem I 9, the stem isequipped with an internal bead means II for the purpose of interlockingwith the groove I! in the regulator. when the regulator 22 is integralwith a pipe stem 2|, the pipe stem is provided with a band 23. The band23 may be eliminated as shown in Figure 5 or it may be inserted thereinas shown at 24 in Figure 6. The, regulator may be constructed with anintegral end wall 25 to provide a chamber 26, and the bite end of thestem is provided with av cap 21 having an internal head 28 whichinterlocks in a groove 29 on the stem to hold the cap in place. The capis provided with the usual egress and ingress openings.

thirdly, to permit moisture and air in the oral cavity to mix with thesmoke before the smoke enters the mouth of a smoker; and fourthly, toincrease the length of the smoke travel by changing the direction of thesmoke from one 40* The operation of the device is as follows. The unitis stretched over or inserted in the end of the pipe stem and fixed toplace. The smoke is then drawn from the bowl .to the mixing chain-A5ber,from which it later travels in an upward direction through an egressinto the-mouth or the smoker. When the smoke enters the mixing chamberor expansion chamber it is turned from its original direction at anangle of ap- 5 proximately 90 degrees therefrom. After leavingthe mixingchamber it then travels upward through the egress into the oral cavityof the smoker, and instead of hitting or striking the I tongue first, itstrikes against. the palate or the As the smoke leaves the end of apipestem it is travelling at a high velocity into the mixing chamber. Inthe mixing chamber it ex-' pands and rotates centripetally therein; suchex-" pansion and rotating causing the moisture and air in the mouthtoenter through the small in-- gress into the mixing chamber where itbecomes mixed with the smoke. Such mixing causes the temperature of thesmoke toqdrop, so that on leaving the mixing chamber it travels throughthe large egress to strike the palate instead of the tongue. As thesmoke leaves the egress it again expands into a large cavity or oralcavity, which expansion reduces the temperature and pressure, thusrendering the smoke non-irritatv .ing to the mucous membrane lining theoral cav-' in the mixing chamber, much of the nicotine contained thereinis thrown therefrom, and leaves the mixing chamber by bleeding from thesmall ingress in the bottom side of the device.

As the smoke travels from the mixing chamber into the mouth, it isconstricted as it flowsthrough the large egress. This constricting orsqueezing of the moisture laden causes moist air from the oral cavity tobe sucked or drawn through the ingress and then into the hot or warmsmoke where it thoroughly mixes.

Any saliva or nicotine which might find its way into the mixing chambermay drain through the ingress in the bottom of the device into the mouthof the smoker, from which it may be eliminated. In this manner thedevice tends to prevent the saliva and nicotine from being forced backinto the pipe stem as is now found in the ordinary smoking pipe.

Again as the smoke expands in the mixing chamber, and as it passesthrough the egress it has a tendency to force the saliva away from theegress thuspreventing its entry into the chamber from that point. Theexpansion of the smoke in the chamber will also prevent the saliva fromentering into the small ingress. In order that this invention willfunction according as herein written it is to be understood that theingress is extremely small in cross section when compared smoke throughthe egress with the egress in cross section. By having the egress verylarge in cross section compared with the ingress cross section, thesmoke as it passes I through the stem into the expansion chamber of theunit will on its expansion therein draw or suck moisture from a smokersmouth into the chamber, and while this process is going on the moistureladen smoke flows from the large egress into the mouth of a smoker.

While I have herein shown and described a preferred arrangement, it willbe readily understood that changes and modifications therein may befound desirable or essential in meeting the various exigencies of use,and I desire to be understood as reserving the right to make any and allsuch changes or modifications as may be found desirable or essential inso far as the same may fall within the spirit and scope of the inventionas expressed in the accompanying claim when broadly construed.

What I claim is: I

In a smoke regulator for pipes and the like, com-- prising, a chamberedportion; a chamber therein; a smoke egressin the upper portion of thechambered portion; an air ingress in the lower portion of the chamberedportion, and substantially below the smoke egress; and a stem attachingportion integral with the chambered portion.
